Zone3 Thermo-Tech Changing Robe

Waterproof, Windproof & Sustainably Built

Built for open water swimmers, triathletes, and outdoor explorers, the Zone3 Thermo-Tech Changing Robe is your essential companion for staying warm, dry, and protected in all conditions. Whether you’re changing after a swim, braving cold sidelines, or layering up for coastal adventures, this robe delivers unmatched performance and comfort—rain or shine.

Crafted with a recycled polyester outer shell, the robe features BIONIC-FINISH® ECO technology for eco-friendly waterproof and windproof protection. Inside, the luxurious Sherpa fleece lining wicks away moisture while trapping body heat, keeping you warm and comfortable in the harshest environments.

The design includes thoughtful details to make every transition seamless—like a tapered fit for better mobility, an adjustable oversized hood, and hook-and-loop wrist closures for a secure, weather-tight seal. The storm flap with poppers keeps out wind and rain, and with five storage pockets, including two zipped compartments, all your essentials stay close and protected.
